Yeah it's weird- I see nothing about region coding on any Blu-Ray box and yet once in a while I'll get a disc from another country that gives a region code error so it must exist. Avid on Mac or PC? Really the only option right now short of spending a fortune or hiring someone else is Adobe Encore.

The good news that unless you plan to replicate your Blu-ray disc, you won't have to worry about region settings. This is because regional settings are applied at the replication stage and only at the replication stage. So if you are using Encore as your Blu-ray Authoring tool then you are good to go.

If you are looking to replicate your Blu-ray discs then you might want to look at a different Blu-ray Authoring tool.
